Binding a subset of columns from a Datatable to RadGridView

There are several other posts that looked similar and I used their code to come close but I am still having problems.

Problem: I have a datatable with a number of columns which I have bound to the radgridview. This works. What I want to do now is restrict the columns based on additional data in the view model. The modelview contains the datatable and the columns which I would like to bind. I am somewhat new to WPF and MVVM. I used the example from this post http://www.telerik.com/forums/column-collections but again it didn't work as I expect.

Thank you for any suggestions or code.

Collection editor cannot 'add' or 'delete'

I'm using auto generating for a object which has a property of type string[].
the 'add' and 'delete' button are grayed out.
I tried to change the property type to List<string> and 'delete' would be usable but 'add' still not.
Could you give me some example of how to enable the full functionality of collection editor?>

The property definition in the object bind to RadPropertyGrid:

string[] _mdAddresses;
public string[] MdAddresses
{
get { return _mdAddresses; }
set { _mdAddresses = value; }
}

[Solved] Shrinking of a container with grouped elements where the container is part of the group

Hi,

I have the following problem:

If you shrink a container (by dragging with the mouse from one of the container corners), that is in a group with its content, both the container and its content is shrinking.
{See Pic1}

Unfortunately, you can shrink the container only as small as the content was before the start of the shrink operation.
{See Pic2}

This behavior seems to be ok if the content do not shrink with the container because of the container should not be smaller as its content.
But why do the shrink operation stops if the content is shrinking too?

Regards,

Create Border for smart label in code behind

I have RadCartesianChart and i am create the AreaSeries view code behind:

RadCartesianChart chart = new RadCartesianChart();

chart.HorizontalAxis = new CategoricalAxis();

chart.VerticalAxis = new LinearAxis();

chart.HorizontalAxis.Visibility = System.Windows.Visibility.Collapsed;

chart.VerticalAxis.Visibility = System.Windows.Visibility.Collapsed;

// Get the style

Style smartLabelStyle = (Style)this.Resources["labelStyle"];

// Create new labelDefinition and set its DefaultVisualStyle property

ChartSeriesLabelDefinition labelDefinition = new ChartSeriesLabelDefinition()

{

DefaultVisualStyle = smartLabelStyle,

Format = "{0:N2}",

Margin = new Thickness(-40, 0, 0, 0)

};

MyInstanse = new AreaSeries(); // this is my series

MyInstanse .ShowLabels = true;

MyInstanse .LabelDefinitions.Add(labelDefinition);

chart.Series.Add(MyInstanse);

And this is my XAML label style:

<Style x:Key="labelStyle" TargetType="TextBlock">

<Setter Property="Foreground" Value="Gainsboro" />

<Setter Property="Background" Value="Transparent" />

</Style>

So all i want to add is border around my Label like in this example:

With standard WPF TabControl it's possible changing tab using standard keyboard shortcut CTRL+TAB to move next and CTRL+SHIFT+TAB to move backward.

[Solved] AutomationProperties not reqognized by Narrator

I've been using some usefull telerik controls for a while, at this point I'm adding some more options voor accessibility to my applications. Narrator or other screen readers are able to read AutomationProperties like Name and HelpText. But when setting these properties on the RadRichTextBox they are not reqognized by windows and the applications reading the AutomationProperties (tool to check: Inspect)

The AutomationMode of the Telerik AutomationManager is already set to FrameworkOnly. When something else is selected all my automationproperties on controls are ignored.

Here is the used xaml:

01.<telerik:RadRichTextBox HorizontalAlignment="Stretch"

02. VerticalAlignment="Stretch"

03. x:Name="radRichTextBox"

04. BorderThickness="0"

05. Margin="0,2,0,0"

06. DocumentInheritsDefaultStyleSettings="True"

07. Focusable="True"

08. FontSize="13"

09. FontFamily="Segoe UI"

10. AutomationProperties.Name="Message for chat">

11. <i:Interaction.Behaviors>

12. <behaviors:TelerikRichTextBoxOptionsBehavior />

13. <behaviors:ChatRadTextBoxBehavior />

14. </i:Interaction.Behaviors>

15. <telerik:RadRichTextBox.InputBindings>

16. <KeyBinding Modifiers="Control"

17. Key="Tab"

18. Command="{Binding Path=DataContext.NextTabCommand, RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}}" />

19. <KeyBinding Modifiers="Control+Shift"

20. Key="Tab"

21. Command="{Binding Path=DataContext.PreviousTabCommand, RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}}" />

22. </telerik:RadRichTextBox.InputBindings>

23.</telerik:RadRichTextBox>

24.<telerik:TxtDataProvider x:Name="TextDataProvider"

25. Text="{Binding PlainContent, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

26. RichTextBox="{Binding ElementName=radRichTextBox}" />

Any suggestions how I can fix this or about what I'm doing wrong?

ItemTemplateSelector not working

I am trying to use ItemTemplateSelector for RadOutlookBar because I want the selected Item to look different from the non selected. Using ItemTemplate works fine but when I use an ItemTemplateSelector the constructor for that custom DataTemplateSelector is called but method SelectTemplate is never called. I am using Version 2013.3.1316.45.
